A capstan winch provides a significant advantage in tension management because it generates a consistent pulling force from start to finish. In contrast, a drum winch's pulling force decreases as more rope or cable spools onto the drum, increasing the drum's effective diameter. A capstan winch's design, which does not store the rope, completely eliminates this issue. The pulling force remains constant throughout the entire pull, making it the ideal choice for long-distance projects and applications where precise tension control is critical to prevent damage to the cable.
